Question

Which of the following types of corrosion has been seen in stainless steels in high purity water containing oxygen?

(a) Cracking of solution-quenched stainless steel only

(b) Intergranular attack and cracking of solution-quenched steel

(c) Intergranular attack only

(d) Neither intergranular corrosion nor cracking of solution-quenched steel

I had been asked this question during an interview for a job.

The origin of the question is Environments topic in section Other Environments of Corrosion Engineering

Answer 1

Right answer is (b) Intergranular attack and cracking of solution-quenched steel

To explain I would say: Intergranular corrosion and cracking of solution-quenched stainless steel and alloys have been observed in high-purity water containing oxygen.
